Chat plugin: is there a way to move the private chat box up where it is visible?

I installed the recent chat update. It has moved the private chat box from the lower right of the current screen where I originally had it to the lower left of the bottom of whatever page I am on. It is not visible until you scroll all the way down that page and the beep doesn't come with the message anymore to notify that it has been used. We have accidentally found it much after the fact. Thanks in advance for your help. Linda
